Abstract (en)
[origin: EP0241973A2] A cutting insert for machining, in particular for recessing, has at least one curved cutting edge (1) or a cutting edge (1) composed of one or more curved and/or straight sections, adjoining which cutting edge (1) without a transition is a correspondingly formed rake face (3). To make possible optimum chip deformation and at the same time to obtain a machining surface which runs exactly parallel to the cutting edge (1), the flank (3) is adapted to the respective shape of the cutting edge (1) in such a way that the perpendicular projection of the cutting edge (1) to a plane (E) produces a straight line, a normal (N) of the plane (E) to the cutting edge (1) enclosing with the flank (3) at least approximately the rake angle ( alpha ) maintained during the machining. <IMAGE>
